Chapter 6 Mass

What is the standard unit of mass?

How does mass differ from force?

page 6-2a In the first paragraph it would be better to say that the astronaut is apparently weightless. The astronaut still has a weight. Can you tell me why this is true?

Have you ever experienced a situation similar to Figure 1?

Recoil Experiments

We will do the air track demo described in the text.

Describe qualitatively the mass of an object that is difficult to put into motion.

page 6-3 Does equation 1 describe the value of the mass of one object?

Properties of Mass

Why is it important that the ratio does not change as the strength of the spring changes?

Standard Mass

What is the standard of mass? Where is it located?

page 6-4 Does mass add following the rules of normal addition?

Does mass have a direction?

Describe the operation of a double pan balance.

page 6-5 Inertial and Gravitational Mass

What type of mass is measured in a recoil experiment?

What type of mass is measured on a double pan balance?

*Are these two types of mass equivalent to each other?

Mass of a Moving Object

page 6-6 Relativistic Mass

Why does the text conclude that the ratio of masses must change as the speeds approach the speed of light? Which object discussed in the text has the greatest change in its mass?

page 6-6b Why does increase in the mass of the electron prevent the electron from moving faster than the speed of light?

Beta Decay

What leaves the nucleus in a beta decay?

Electron mass in Beta Decay

page 6-8 Plutonium

If your body was only made of protons, how many protons would be in your body?

Which has more mass: one electron or one proton?

What is the ratio of their rest masses?

You should do the calculation in exercise 2.

page 6-9

Protactinium 236

You should do the calculation in exercise 3.

You should do the calculation in exercise 4.

page 6-10 The Einstein Mass Formula

What is an easy method to calculate the relativistic mass of an object?

At what speed will an object have a mass four times its rest mass?

page 6-11 Nature’s Speed Limit

*What is inertia?

Zero Rest Mass "Particles"

page 6-12

*What is a photon?

What is the value of 0/0?

Is Einstein’s mass formula used to calculate the mass of a photon?

page 6-13 Neutrinos

How are neutrinos detected?

Solar Neutrinos

page 6-14 Why might astronomers want to detect solar neutrinos?

What is one possible solution to the deficiency problem of solar neutrinos?

Neutrino Astronomy

Not all of the energy from the supernova is radiated in the form of neutrinos. How do you know my statement is correct?
